Cinelock Anti-Twist Cradle for Arri
This adapter allows a Cinelock quick release to attach to any standard Arri Accessory hole pattern without twisting. The Arri accessory holes are 3/8-16 UNC threaded holes with a 4-way locating hole pattern, and are found on Arri Alexa and Amira handles, Arri PCS accessories, and aftermarket accessories. This cradle is machined from 6061 aluminum, anodized black, and features two stainless steel 3mm locating pins. One 16mm long 3/8"-16 flat screw is included to compensate for the cradle's 4mm depth. The Cinelock Anti-Twist Arri Cradle is a perfect companion to the MDR Cheeseplate to mount a Preston MDR on the camera right side of an Alexa.
Cinelock Anti-Twist Cradle for Preston
This adapter allows a Cinelock quick release to attach to a Preston Hand Unit (HU3 or HU2) without twisting. It fits over the rectangular accessory block normally used for a Microforce bracket. Super handy to quickly attach and detach an Ultralight arm or Noga arm to hold a monitor, or mounting the hand unit to a stand, etc. The anti-twist cradle is machined from 6061 aluminum and anodized black. Please note that the Preston mounting block on an HU2 is impractical to use due to the large overhanging battery unless you have adapted your HU2 with an Omnishot.
Cinelock Anti-Twist Cradle for SmallHD DP7
This intermediary adapter allows a Cinelock quick release to attach to a SmallHD DP7 monitor without twisting. Access to power port and HDMI in port (depending on the size of your cable) is unimpeded, but it does block the USB port. The anti-twist adapter is 3D-printed nylon. I do not stock these; they are available for you to order directly from Shapeways.
